“…In the present study, macrofauna from the mangrove site were dominated by sub-surface deposit feeding tubificid oligochaetes (Ciutat et al, 2006;Giere, 2006), which agrees with previous mangrove and salt-marsh studies showing dominance by tubificids (Schrijvers et al, 1995;Levin et al, 2006). Their dominance in the community may be a function of their ability to cope with hypoxic and sulphidic conditions (Giere, 2006).…”

Abstract. To evaluate how mangrove invasion and removal can modify short-term benthic carbon cycling and ecosystem functioning, we used stable-isotopically labeled algae as a deliberate tracer to quantify benthic respiration and C-flow over 48 h through macrofauna and bacteria in sediments collected from (1) an invasive mangrove forest, (2) deforested mangrove sites 2 and 6 years after removal of above-sediment mangrove biomass, and (3) two mangrove-free control sites in the Hawaiian coastal zone. Sediment oxygen consumption (SOC) rates averaged over each 48 h investigation were significantly greater in the mangrove and mangrove removal site experiments than in controls and were significantly correlated with total benthic (macrofauna and bacteria) biomass and sedimentary mangrove biomass (SMB). Bacteria dominated short-term Cprocessing of added microalgal-C and benthic biomass in sediments from the invasive mangrove forest habitat and in the 6-yr removal site. In contrast, macrofauna were the most important agents in the short-term processing of microalgal-C in sediments from the 2-yr mangrove removal site and control sites. However, mean faunal abundance and C-uptake rates in sediments from both removal sites were significantlyCorrespondence to: A. K. Sweetman (asw@niva.no) higher than in control cores, which collectively suggest that community structure and short-term C-cycling dynamics of sediments in habitats where mangroves have been cleared can remain fundamentally different from un-invaded mudflat sediments for at least 6-yrs following above-sediment mangrove removal. In summary, invasion by mangroves can lead to dramatic shifts in benthic ecosystem function, with sediment metabolism, benthic community structure and shortterm C-remineralization dynamics being affected for years following invader removal.

“…Their dominance in the community may be a function of their ability to cope with hypoxic and sulphidic conditions (Giere, 2006). However, the small, slender body size of tubificids may also allow them to easily inhabit the dense, root fiber network present in mangrove sediments (Levin et al, 1998;Demopoulos, 2004).…”

“…Enchytraeids (Oligochaeta), commonly known as potworms, form a large and widely distributed group of saprophagous organisms, which inhabit the litter layer and the upper mineral soil of many terrestrial and supralittoral ecosystems (Didden, 1993;Giere, 2006). They play important functions, namely as soil structure promoters, in the decomposition of dead organic matter and nutrient mobilization (Petersen and Luxton, 1982;Didden, 1993).…”

SUMMARYEnchytraeus albidus is a freeze-tolerant enchytraeid found in diverse habitats, ranging from supralittoral to terrestrial and spanning temperate to arctic regions. Its freeze tolerance is well known but the effect of salinity in this strategy is still poorly understood. We therefore studied the combined effect of salinity (0, 15, 35, 50‰ NaCl) and sub-zero temperatures (−5, −14, −20°C) on the freeze tolerance of E. albidus collected from two distinct geographical regions (Greenland and Germany). A full factorial design was used to study survival, and physiological and biochemical end points. The effect of salinity on the reproduction of German E. albidus was also assessed. Exposure for 48h to saline soils prior to cold exposure triggered an increase in osmolality and decrease in water content. Worms exposed to saline soils had an improved survival of freezing compared to worms frozen in non-saline soils, particularly at −20°C (survival more than doubled). Differential scanning calorimetry measurements showed that the fraction of water frozen at −5 and −14°C was lower in worms exposed to 35‰ NaCl than in control worms. The lowering of ice content by exposure to saline soils was probably the main explanation for the better freeze survival in saline-exposed worms. Glucose increased with decreasing temperature, but was lower in saline than in non-saline soils. Thus, glucose accumulation patterns did not explain differences in freeze survival. Overall, the physiological responses to freezing of E. albidus from Greenland and Germany were similar after exposure to saline soils. Soil salinity up to 30‰ improved reproduction by a factor of ca. 10.

“…Giere (2006), in a brief analysis of the recent literature dealing with the ecology and biology of marine oligochaetes, stated that the ecological role of oligochaetes in eulittoral ecotones "requires at least as much intense scientiWc attention as do polychaetes" and considers that "the lack of new ecological and biological studies on marine Oligochaeta, since the 1982 review (Giere and Pfannkuche 1982), is disturbing".…”

Polychaetes and oligochaetes associated with intertidal rocky shores in a semi-enclosed industrial and urban embayment, with the description of two new species

The species composition and relative abundance of the annelid benthic macrofauna (Polychaeta and Oligochaeta) inhabiting the rocky intertidal zone of the ria of Ferrol (Galicia, NW Spain) were studied during Weld collections, from 2000 to 2002. A total of 14,619 specimens (11,585 polychaetes belonging to 76 species and 24 families and 3,034 oligochaetes belonging to 18 species and two families) were collected from 98 quantitative samples taken from 13 sampling sites. The general spatial distribution of the annelid fauna reXects an increase of the diversity from the inner to the outer part of the ria. The general patterns found in the annelid composition suggest that the assemblages were dominated by oligochaetes in the inner sheltered sampling sites and polychaetes in the outer more exposed sites. Several faunistical and taxonomical remarks on selected species are presented. Two new species of oligochaetes are described: Coralliodrilus artabrensis sp. n. and Pirodrilus fungithecatus sp. n. (Naididae, Phallodrilinae). A new biological index, based on the oligochaete/ polychaete ratio (O/P), is proposed as tool to evaluate environmental quality and to monitor future changes in the environment.
